Due to COVID we are pushing back IBU Open to June 21 -27.


This competition is BJCP/AHA sanctioned, and is open to any amateur homebrewer age 21 or older.

All Entries must be paid via Paypal through the competition website, and must be paid before you can print your entry labels. The entry limit for IBU Open 2021 is set to 300 Paid entries. Be sure to pay your entries early enough to make sure they're accepted.

All mailed entries must be received at the mailing location by the shipping deadline - please allow for shipping time.

All entries will be picked up from drop-off locations the day of the drop-off deadline.

All entries must be handcrafted products, containing ingredients available to the general public, and made using private equipment by hobbyist brewers (i.e., no use of commercial facilities or Brew on Premises operations, supplies, etc.).

The competition will use the newer style Structured Score Sheets designed for the National Homebrew Competition.

The competition organizers are not responsible for mis-categorized entries, mailed entries that are not received by the entry deadline, or entries that arrived damaged.

The competition organizers reserve the right to combine styles for judging and to restructure awards as needed depending upon the quantity and quality of entries.

Qualified judging of all entries is the primary goal of our event. Judges will evaluate and score each entry. The average of the scores will rank each entry in its category. Each flight will have at least one BJCP judge.

Brewers are not limited to one entry in each category, but will be limited to one entry per subcategory.

The competition committee reserves the right to combine overall style categories based on number of entries. All possible effort will be made to combine similar styles. All brews in combined categories will be judged according to the style they were originally entered in.

The Best of Show judging will be determined by a Best of Show panel based on a second judging of the top winners.

Bottles will not be returned to entrants.
